摘要： The present disclosure is directed towards the prevention of high voltage instabilities within X-ray tubes. For example, in one embodiment, an X-ray tube is provided. The X-ray tube generally includes a stationary member, and a rotary member configured to rotate with respect to the stationary member during operation of the X-ray tube. The X-ray tube also includes a liquid metal bearing material disposed in a space between the shaft and the sleeve, a seal disposed adjacent to the space to seal the liquid metal bearing material in the space, and an enhanced surface area material disposed on a side of the seal axially opposite the space and configured to trap within the enhanced surface area material liquid metal bearing material that escapes the seal.

The target assembly includes a target and a spiral groove bearing (SGB) configured to support the target. The SGB includes a rotatable component having a first surface and a first material attached to the first surface, a stationary component having a second surface and a second material attached to the second surface, the stationary component positioned such that a gap is formed between the first material and the second material, and a liquid metal positioned in the gap. At least one of the first and second materials has a thickness greater than 0.1 mm.
